Recently I have been updating a list of the most recent penalties in the Champions League knock-out phase and, also by the amount of reactions, I think it is quite interesting: only four of the last thirteen penalties in the Champions League KO round have been scored; a not so staggering 31%.
Super-subs, the sub effect, pinch hitters and more. Players like Jermain Defoe (23 Premier League goals as a sub), Nwanko Kanu (17), Ole-Gunnar Solksjaer (17) and Javier Hernández (14) have done a lot of work to promote this terminology over the past decade(s). But how certain are those concepts? Are their players that consistently score more goals coming on as a sub? And what is the general tendency; do subs, fitter than starters when they come on, score more goals then starters? Let’s see.
I have been writing quite a lot on Premier League substitutions lately and here is an overview of the posts:
- Premier League substitutions: 1. What and When?
- Premier League substitutions: 2. The Decision Rule
- Premier League substitutions: 3. Do subs score more than starters?
- Premier League substitutions: 4. The double-substitution at half time
- Premier League substitutions: 5. Olivier Giroud (draft)
- Premier League substitutions: 6. Jürgen Klopp
ALL DATA COMES FROM DATAFACTORY
As argued in one of my previous blogs, building on the “Decision Rule” from Myers, Premier League managers could increase their chances of turning around a game if they would make earlier substitutions. As can be seen here managers on average implement their first, second and third substitutions in the minutes 62. 72 and 81 respectively.
Liverpool and Man United played a close but rather dull game at Anfield Road last night (17/10/2016). The Red Devils held the Reds to only 9 shots, their lowest tally in a Premier League home game in the last 2 seasons (the current and last season that is), while they themselves also could not get more than 7 attempts.
Data that is discussed in this blog was described here.
Replicating Myers’ study to substitutions
WHY am i digging this up?
Although there is seemingly very little a manager can do during a game and substitutions seem to be their main way to have an impact on the game, there is very little discussion about them. When getting the data on Premier League subs, as discussed before, I remembered some statements from the book “The Numbers Game” where a study from Myers is mentioned. I wanted to see how much of his conclusions hold true over a larger time period in the Premier League (the dataset from Myers covers only one season).
Tactics have been transmitted to the players, set pieces have been prepared (or more likely not..) and opponents have been thoroughly studied. Then it’s game time and the manager sees his influence slip out of his hands. There seems to be only so much he can do during the 90 minutes. Walking impatiently along the sideline, shouting at the fourth official and handing notes to throw-in takers is probably not going to do it, but one of the obvious things he can do to try to impact an on-going game is to bring on substitute players. Little has been written on this matter, so here is my (first) try.
This blog was written on 26/4/2015, after Round 35 of the Premier League 2015/16.
You know that situation when you leave the pitch when your team is winning 2-1? At the end of the 90 minutes the opponents have turned everything around and won the match 2-3. Stubborn as you are you tell your manager and teammates that you DID win the game, having left the field in a winning situation.
Taking those situations into account we can calculate the effectivity of each player in his team: how many goals does his team score when he is on the pitch compared to when is not present? And what impact does he have on the total goal difference?
Here’s a preview for Round 30 of the Premier League, which we’ll be played over different weeks.
Leicester City, last year bottom of the table after 24 matchdays, is now leader of the Premier League. What happened to the other teams in the same position in the Premier League era?
